Specification of Letters Patent.

Application filed December 4, 1917. Serial No. 205,438.

T 0 all whom it may concern:

Be it known that I, CHARLES Wnsnnr FoRBEs, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in F ireplace-Furnaces, of which the following is a specification.

My object is to improve the details of construction of a fire place furnace with a View of increasing theefiiciency by increasing the radiation, and my invention consists of the'novel features herein shown, described and claimed.

Figure 1 is a front elevation of a fire place furnace embodying the principles of my invention.

Fig. 2 is a sectional elevation on a plane parallel with Fig. 1.

I Fig. 3 is a horizontal section on the line 3-3 of Fig. 2.

Fig. 4 is a vertical cross-section on the line 4-4 of Fig. 2.

Fig. 5 is a vertical cross-section on the line 5 -5 of Fig. 2.

The outer casing is made of sheet metal and consists of the back wall 1, the rear side walls 2 and 3 extending forwardly from the back wall, the forward side walls 4 and 5 extending forwardly from the walls 2 and 3, the lower front wall 6 connecting the lower portions of the walls 4 and 5, the upper front wall 7 connecting the upper portions of the walls 4 and 5, the top Wall 8 connecting the upper edges of the walls 4 and 5, the back Wall 9 extending from the rear side of the top wall 8 and connecting the walls 4. and 5, and the top plate 10 connecting the forward upper edges of the walls 4 and 5 and. the upper edge of the wall 6.

The box thus constructed is adapted to slide backwardly into an ordinary fire place, the walls 2 and 3 fitting the walls of the fire place and the walls 4 and 5 extending forwardly from the walls of the fire place.

The back wall 1 extends straight up from the floor substantially half way to the top of the fire place and then is inclined forwardly as it goes upwardly. A damper opening 11 is formed between the upper edge of the wall 1 and the lower edge of the wall 9 and a damper 12 is pivotally mounted to close the damper opening and to adjust the size of the opening, said damper 12 being operated by a rod 13 explate 10 to the wall tending through the Walls 7 and 9 and having a handle 14 upon its forward end.

The fire box comprises the bottom 15 connected to the rear edge of the top plate 10, the back 16 extending upwardly from the rear edge of the bottom 15 and connected to the upper inclined portion of the back wall 1 by brackets 17, the side walls 18 and 19 extending upwardly from the bottom 15 and connected to the back wall 16 and to the upper part of the'back wall 1, and the top '20 connecting the 'upper edges of the side walls 18 and 19 arid the lower edges of the walls 7 and 9,so as to locate the fire box centrally in the. outer casing.

Smoke flues 2'1 and 22 lead through the upper parts of the side walls 18 and 19 and downwardly to the smoke headers 23, and smoke flues 24 lead upwardly from the forward ends of the smoke headers 23 through the wall 9 to the throat 25 in the chimney 26.

The smoke flues are located in the side air chambers 27 and 28 between the walls 2 and 18 and the walls 19 and 3.

Water pans 29 and 29'- are located upon the floor of each of the air chambers 27. and 28. A lid 30 is formed'in the top plate 10 so that access may be had to the regi'ste 30' in the central floor.

Cold air intake registers 31 and 32 are formed through the wall 6 'to admit cold air under the top plate 10' to the chamber 33 underv the fire box, and hot air discharge registers 34 and 35 are formed through the wall 7 to discharge hot air from the chambers 27 and 28. v/

The tile walls or panels 36 and 37 connect the forward edges'of the walls 4 and 18, and 19 and 5, and extend from the top 7 and an ornamental tile wall 38 connects the lower ends of the walls 36 and 37 above the bottom 15. A railing, 39 extends from the outer sides of the panels 36 and '37 forwardly to the posts 40' and 41 and connects said posts together. i Y

Any desired fuel, such as gas, oil, wood,

coal, and the like, may be burned upon the Q 4 'i'eeaoaa The cold fresh air will pass inwardly through the registers 31 and 32 to the cha1nber 33 and circulate all around the fire box and around the smoke fiues and pass outwardly through the registers 34 and 35.

'Various changes may be made in the details of construction without departing from the spirit of my invention as set up in the following claim.

I claim:

In a fire place furnace, a lower back wall, rear side Walls extending forwardly from the back wall, forward side walls extending forwardly from the rear side walls, a lower front Wall connecting the lower portions of v the forward side walls, an upper front wall connecting the upper portions of the for Ward side walls, a top Wall connecting the upper edges of the forward side walls, an upper back wall extending from the rear the upper edges of the forward lower portions of the forward side walls, there being a damper opening between'the lower and upper back walls, a damper for the damper opening, a fire box constructed between the side walls, there being a chamber at each side and a chamber below the fire box, and smoke' fiues leading laterally from the fire box and downwardly in each side chamber to a smoke header and a'flue leading upwardly in each side chamber from the smoke header and through the upper back wall.

In testimony whereof I have signed my name to this specification.
